A STUDY ON NEW EVALUTION METHOD OF AGGREGATE SCATERING IN POROUS ASPHALT

Localized damage of porous asphalt cannot be evaluated by rutting-cracking-IRI which are conventional damage evaluation indexes of pavement Surface aggregate peeling due to deterioration of binder is scattered over a wide area of the Shizuoka prefecture section of the Tomei Expressway. Since this damage cannot be evaluated by the conventional evaluation index, the authors investigated the new index to evaluate the area of surface aggregate peeling the traverse profile data. They also tried to visualize the damaged state by coloring the surface aggregate peeling on a view of upper surface. As a result the more evaluation criteria (Level I, II, III, IV, V) Progressed by deterioration evaluation method The more area of surface aggregate peeling increased.
